Google Says Most Google Code Software Licensed GPLv3
At OSCON, Google's open source guru Chris DiBona said that more than half of the GPL licensed code hosted on Google Code is GPLv3.
InternetNews' Sean Michael Kerner wrote, "Just to mix and match some stats here, a year ago I wrote about a Black Duck report that showed the GPLv3 still lagging behind the GPLv2. As with lots of other things, sometimes adoption is just a matter of time."
While GPLv2 will remain a contender for years to come, since Richard Stallman released GPLv3 in 2007, it's gaining ground quickly.
